Imagine a world if you will. Suspend your disbelief if you will. In the same way that children born in 2005 and above have no concept of a world without smart phones and computers. Imagine a world 30 to 50 years from now, where each country has a supercomputer AI that's sorts the population into castes based on their genetic strengths. Would the humans born into that system see it as wrong? Would they see it as oppression? Would it not make sense for this system to be in place? Why would you have a human without the warrior gene in a warrior role? Why would you have a human with great physical genetics not in a sporting or physical entertainment role? Why would you have a human with great genetics for engineering and math in a doctors/healers role?
